PREFACE

In the preparation of this work, the object has been to cover not only the
several processes of welding, but also those other processes which are so
closely allied in method and results as to make them a part of the whole
subject of joining metal to metal with the aid of heat.

The workman who wishes to handle his trade from start to finish finds that
it is necessary to become familiar with certain other operations which
precede or follow the actual joining of the metal parts, the purpose of
these operations being to add or retain certain desirable qualities in the
materials being handled. For this reason the following subjects have been
included: Annealing, tempering, hardening, heat treatment and the
restoration of steel.

In order that the user may understand the underlying principles and the
materials employed in this work, much practical information is given on the
uses and characteristics of the various metals; on the production, handling
and use of the gases and other materials which are a part of the equipment;
and on the tools and accessories for the production and handling of these
materials.

An examination will show that the greatest usefulness of this book lies in
the fact that all necessary information and data has been included in one
volume, making it possible for the workman to use one source for securing a
knowledge of both principle and practice, preparation and finishing of the
work, and both large and small repair work as well as manufacturing methods
used in metal working.

An effort has been made to eliminate all matter which is not of direct
usefulness in practical work, while including all that those engaged in
this trade find necessary. To this end, the descriptions have been limited
to those methods and accessories which are found in actual use today. For
the same reason, the work includes the application of the rules laid down
by the insurance underwriters which govern this work as well as
instructions for the proper care and handling of the generators, torches
and materials found in the shop.

Special attention has been given to definite directions for handling the
different metals and alloys which must be handled. The instructions have
been arranged to form rules which are placed in the order of their use
during the work described and the work has been subdivided in such a way
that it will be found possible to secure information on any one point
desired without the necessity of spending time in other fields.

The facts which the expert welder and metalworker finds it most necessary
to have readily available have been secured, and prepared especially for
this work, and those of most general use have been combined with the
chapter on welding practice to which they apply.

The size of this volume has been kept as small as possible, but an
examination of the alphabetical index will show that the range of subjects
and details covered is complete in all respects. This has been accomplished
through careful classification of the contents and the elimination of all
repetition and all theoretical, historical and similar matter that is not
absolutely necessary.

Free use has been made of the information given by those manufacturers who
are recognized as the leaders in their respective fields, thus insuring
that the work is thoroughly practical and that it represents present day
methods and practice.
